The current density shall be calculated at the point(s) of maximum current density (i.e., greatest current (see A.3.5.5a) per unit cross section) for the specific device type and schematic or configuration. Individual device calculations are not required when appropriate documented design rules or requirements have been used, which limit or control the current density in the resulting design. a. Use a current value equal to the maximum continuous current (at full fanout for digitals or at maximum load for linears) or equal to the simple time-averaged current obtained at maximum rated frequency and duty cycle with maximum load, whichever results in the greater current value at the point(s) of maximum current density. This current value shall be determined at the maximum recommended supply voltage(s) and with the current assumed to be uniform over the entire conductor cross-sectional area. b. Use the minimum allowed metal thickness in accordance with manufacturing specifications and controls including appropriate allowance for thinning experienced in the metallization step. The thinning factor over a metallization step is not required unless the point of maximum current density is located at the step. c. Use the minimum actual design conductor widths (not mask widths) including appropriate allowance for narrowing or undercutting experienced in metal etching. d. Areas of barrier metals, not intended by design to contribute to current carrying capacity, and nonconducting material shall not be included in the calculation of conductor cross section. Thick film conductors multichip substrates (metallization strips, bonding interfaces, etc.) shall be designated so that 2 no properly fabricated conductor shall dissipate more than 4 watts/cm when carrying, maximum design current. A.3.5.5.1 Metallization thickness. For class level S microcircuits, the minimum metallization thickness shall be 8,000 & (800 nm) for single level metal and for the top level of multi-level metal, and 5,000 & (500 nm) for the lower level(s) of multi-level metal. In all cases, the current density requirements of A.3.5.5 shall also be satisfied. A.3.5.5.2 Internal wire size and material. For class level S microcircuits, the internal wire diameter shall be .001 inch minimum (0.03 mm) and the internal lead wire shall be of the same metal as the die metallization. A.3.5.5.3 Internal lead wires. Internal lead wires or other conductors which are not in thermal contact with a substrate along their entire length (such as wire or ribbon conductors) shall be designed to experience, at maximum rated current, a continuous current for direct current, or an RMS current (peak current divided by 2), for alternating or pulsed current, not to exceed the values established by the following relationship: Reprinted without change. 34 Downloaded from http://www.everyspec.com STANDARDIZATION DOCUMENT IMPROVEMENT PROPOSAL INSTRUCTIONS 1.
